Yes. That can be done. Just google the fork name and then air shaft and you will fine options.

Awesome, thanks Jeff.

Fork travel recommendations by frame manufacturer suggest travel between 140-150mm.  Found the fork I really want but it’s got 160mm travel.

Has anybody over-traveled this frame with a fork that has 10mm more vs recommended travel?  Any recommendations or suggestions or consequences about this?  I usually never go outside of the manufacturers recommendations on anything I build, but in this case I’m not too sure 10mm would make too much of a difference.

Anybody care to educate me a bit on this?
Thx!

Their DCB F140 is just a Carbonda FM1001 but they claim different rear travel for the same shock sizes. Identical geo charts

Yeah, I noticed that, but DIY seems to have a branch and/or warehouse here in USA (GA amd Delaware) and some kind of footprint here in the country I live, so I was wondering if that would be a better option in terms of shipping times or post sale service/warranties.  Frame is still coming from china, just thought they could have the upper hand over Carbonda because of location.  The price of both frames is almost identical at about $1,000-ish shipped…

Input both bikes into this calculator.  To compare hardtail properly, input at the top a negative fork travel for how much sag you have.  Then in the bottom calculations, "Calculated Seated Fit" is saddle to bars.  You'll find that with the same ETT, your saddle to bars will be very close and it's the reach that differs.  So it'll feel similar length while seated, but your body is rotated forward with a bit more weight on the hands, but a steeper STA longer reach bike will feel longer while standing.

The picture visualization is perfect to see how they compare, then if you really like your current fit, you can see how stem, stack, handlebar, etc changes will dial it in, so you can make a good guess at what size components to start with.

Great info, thanks acedeuce802!

Thanks Cerps, it makes complete sense.  The light carbon examples you mention made it pretty easy to understand.  Thanks a million.

I saw an interesting video of why you can't just replicate geometry numbers on a hard tail and full suspension and expect them to feel similar.




The youtuber, Jeff Lenosky, is a skilled biker and settled on a reach 40mm shorter on his hard tail for a similar feel to his full suspension bike after trial and error.

Geometry changes very differently through suspension travel on a hard tail versus a full suspension bike. Even at sag, the bikes with the same reach on the geometry charts have changed in different ways. On a full suspension, the "effective" reach shortens as the suspension squats. On a hard tail, the reach feels like it lengthens. Other geo numbers also probably change quite differently as the suspension squats.

Interesting take, I’ll definitely check the video out…

I didnt  take into account sag too much since I thought that could be adjusted by saddle height, but didn’t consider new reach while  seated down at different saddle heights due to the Seat Angle…

Thx!

Price on the M30?

Thx.
